Hesitation when accelerating on other TLX years
No other TLX model year has enough reports of hesitation when accelerating for a sheet of its own. See every TLX year.
What this problem usually is
This is the narrower sheet inside transmission shudder for a car that pauses before it goes. You press the gas, and for a beat nothing happens, or the engine revs and then the car catches up. What makes it distinct from the wider sheet is timing: the complaint isn't a rough shift at speed but a delay right when you need to move.
What got replaced
Owners who name the part that was replaced mention the transmission (18 reports) and the software (9 reports).
Recalls and investigations
2 recalls on the transmission and drivetrain cover the 2015 model year. A recall on the same system isn't always the same failure, so read the defect text.
In the affected vehicles, the transmission wire harness connections may have insufficient crimps, and, as a result, the transmission may unexpectedly shift to neutral.
The automatic transmission parking pawl may become contaminated or the park rod may become dislodged or broken. This may prevent the transmission from shifting into the Park position.

Should you keep driving it?
This page can't tell you that. 0 of 31 reports involved a crash. Owners who file are the ones who had a bad experience, and nobody checks their reports. If the problem affects steering, braking, power or a fire risk, treat it as a safety fault and have it inspected before a long or high-speed drive.
File your own report with NHTSA. Complaint counts are how a problem gets an investigation. How reports land on this sheet.
